The YamlReference package

This package contains "the" reference YAML syntax parser
(Text.Yaml.Reference), generated directly from the YAML
specifications, as well as sample program (yaml2yeast)
that allows accessing it from the command line, converting
YAML files to YEAST tokens. This is intended to be more of
an "executable specification" for YAML rather than an
actual basis for YAML tool chains. That said, it is
possible to build interesting tools on top of it, such as
the yeast2html YAML syntax visualizer (contained in this
package), pretty printers, etc. This is a streaming parser
that will "immediately" begin to generate output. Updated
to be compatible with the May 11, 2008 working draft.
